During exercise, increased sympathetic nervous system activity leads to vasoconstriction in most visceral organs and vasodilation in skeletal muscle. This differential response is primarily mediated by which adrenergic receptor type in skeletal muscle arterioles?
✓ Correct Answer: Option C
Beta-2 adrenergic receptors in skeletal muscle arterioles cause vasodilation, increasing blood flow during exercise. Alpha-1 receptors in other visceral organs cause vasoconstriction, redirecting blood.
